Abstract (en)
An array substrate, a liquid crystal display and a control method thereof are disclosed according to the invention. The array substrate includes: multiple scanning lines; multiple data lines; multiple pixel units; multiple common lines, where each of the common lines is disposed along a row of pixel units; a common voltage supply line; multiple dual-channel selection switches, where an output terminal of each of the dual-channel selection switches is connected to a set of common lines, two input terminals are connected to a common voltage high level supply line and a common voltage low level supply line respectively, so as to selectively apply a high level or a low level to the common lines. The control method includes: supplying power to a common line corresponding to a scanning line before providing a scanning signal to the scanning line, and maintaining the potential of the common line unchanged during displaying a frame of picture; and inverting the potentials applied to the common line during scanning for a next frame. The embodiments of the invention avoid the problems of the delay of the common voltage Vcom and the Vcom drift during displaying, and improve the displaying effect for an image.
